Northern Lao - European
Cave Project 


Welcome to the Northern Lao - European Cave Project !

The Northern Lao Project is a group of experienced cavers organized within the German Federation of Speleology and the Swiss Society for Speleology. We possess a large speleological expertise which is enlarged by cavers joining from our international partner network. We collaborate with government authorities, NGOs and research institutions to document the caves and karst of the Northern provinces of Lao PDR.

We documented in total around 365 caves with 140 km of cave passages. The results are published in 6 books and talks very given at many conferences. Several caves were developed for ecotourism after exploration by the project. The Chom Ong Cave in the Oudomxay province is the most known which opened to public in 2020. A karst database with all cave locations is maintained that can be made available on request.

The project moved its focus to neighboring Myanmar from 2015 and exploration ceased in the Northern provinces. With the recent developments in Myanmar, the project returns and resumes the documentation of karst in caves in the Northwestern provinces of Bokeo and Sayabouli. We are happy assisting any organisation interested in the beautiful karst of the Lao PDR with our data. Please contact us!
